OIL GRADE INDICATOR Filed June 16, 1934 Patented Nov. 12, 1935 UNITED STATES PATENT OFFICE 15 Claims.

This invention relates to indicating appliances and more particularly to one for designating the proper grade of oil to be used in a certain make of motor car of ascertained model and mileage.

The ordinary chart from which the proper oil grade is found, is of necessity difficult to read due to the great number of factors which must be taken into consideration in reaching. the nal result. Errors inadvertently occur in reading such charts because of the difficulty of focusing the attention on the separate factors involved in the ultimate determination. With such charts there is present the added disadvantage that to check the final result reached, the same hazardous steps must be repeated, at any point of which a mistake can easily be made.

An object of the present invention is to simplify the determination of the proper grade of oil for a particular motor car and thereby minimize chances for error.

Another object is to focus the users attention on the particular factors involved to the exclusion of those which are inconsequential.

A further object is to expedite the steps of determining the proper oil grade.

A still further object of the invention is to facilitate rechecking of the result found.

Other objects will hereinafter appear.

In the drawing showing a preferred embodiment of the invention:

Figure l is a plan view having portions broken away to better show the structure.

Fig. 2 is a plan view with the parts in a different relative position from Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1 on an enlarged scale.

Fig. 4 is a fragmentary view showing the base discs in changed relation from Fig. 1.

In general, the indicating appliance consists of a base part I on which the ultimate result is to be indicated and shiftable parts indicated at 2 carried by the base and which when set in accordance with predetermined data point to the final result.

As here shown, the shiftable parts 2 include a main carrier member 3 having a pivotal connection at 4 with the base. The carrier member 3 has a pointer at 5 which may be set opposite the proper point on scale 6 marked on the base, corresponding to the year model of the motor car in question. This setting constitutes a base position from which a subsequent setting is made.

Pivotally connected at 8 to the carrier member 3, as here shown, adjacent the pointer end thereof, is an index member l. The index of this member I is an opening 9 intermediate of its length, through which informational data I0 marked on the base can be read. The angular setting of member 'I relative to carrier member 3 corresponds to the mileage of the motor car in 5 question. To determine this angular setting, an arm I2 is provided which connects the outer end of the member 'I and the pivotal end of carrier member 3. In the illustrated form of the appliance the pivot pin 4 serves to pivotally connect 10 arm I2 to the carrier member 3. The connected ends of index member I and arm I2 have a pin and slot connection, the pin I3 being carried by member 'I and the slot I4 being formed in arm I2. This slot I4 is graduated as to mileage.

In setting the pin I3 at the point along slot I4 corresponding to the car mileage, the index member 'I will be swung about its pivot pin 8 and the opening 9 will assume a definite position relative to carrier member 3. It will be noted 20 that the pivot points 4, 8 and I3 represent vertices of a triangle of which two sides 4 8 and 8--I3 are xed while the third side 4-I3 is variable. The angular dimension of the angle 4-8-I3 and correspondingly the angular position of index member 'I relative to carrier member 3 is directly proportional to the length of side 4-I3 or the distance between points 4 and I3. For this reason the index opening 9 will be brought to a definite position relative to the carrier member when pin I3 is set at the proper reading along slot I4.

The zero point along slot I4 is so located as to bring pin I3 in the line of centers between pins 4 and 8 when the pin I3v is at the zero point of the slot. The slot I4 projects in a direction away from a line joining pins 4 and 8 as is clear from Fig. l of the drawing.

The informational data III below the path of movement of the index opening 9 is curved 40 to lie on an arc about pivot pin 4. This data shows the proper oil grade to be used as determined by the settings of the several members. If desired this data could be for a particular make of motor car in which case this data would be unchangeable.

However, in order that the appliance will have wider application, means are provided whereby a set of oil grade readings proper for each different make of car may be brought under the path of movement of opening 9. This is accomplished by forming an opening I5 through the discs I6 to which the pivot pin 4 is connected, this opening I5 lying in the path of movement of index opening 9 and through which the read- 55 ings I0 may be made. Various sets of oil grades each corresponding to a particular make of car may then be brought under opening I5. These sets of oil grades are marked on a disc Il also carrying the car names at I8 Which are viewable through opening I9 in disc I6. In the present device, the discs I6 and I1 are pivotally connected by pin 28 at their centers to enable the desired oil scale I0 for a particular car to be brought in position.

As shown in Fig. 3 the under sides of the carrier member 3 and arm I2 are recessed to accommodate the indicator member I and provide a flush under surface,

In using the appliance, the following procedure may conveniently be employed. The name of the motor car in question is iirst brought to opening I9 by relatively rotating discs I6 and I1. Next pointer 5 is brought to the reading on scale 6 corresponding to the car model and held in that position, while the pin I3 is then shifted along the slot I4 to the car mileage as shown in Fig. 2. The oil grade is then read through openings 9 and I5.

Since but one oil scale is exposed, likelihood of error is precluded. To check the final result a glance at the several settings is sufficient and no manipulative steps are required.

The face of disc I6 carries printed instructions at 2| pointing out among other features, allowances to be made in cases of extreme temperatures, repairs to the motor car, high speeds, etc.
